Question

1 - 61. eduardos 12 friends guessed how many jelly beans were in a jar at his birthday party. here is an ogive of their guesses. use the information from the ogive to create a histogram of the original data.

Explanation:

Step1: Identify data intervals

From the ogive, we can identify the intervals of guess - values. For example, the first interval might be from 40 - 60, second from 60 - 80 etc.

Step2: Determine frequency for each interval

The frequency for an interval can be found by looking at the change in the cumulative frequency (represented by the percentile on the ogive). For instance, if the cumulative frequency at 60 is 20 and at 80 is 40, the frequency for the 60 - 80 interval is 40 - 20=20.

Step3: Draw histogram

Use the intervals on the x - axis and the frequencies on the y - axis to draw bars for each interval.

Answer:

A histogram with appropriate intervals on the x - axis (e.g., 40 - 60, 60 - 80, 80 - 100, 100 - 120, 120 - 140, 140 - 160) and frequencies (calculated as above) on the y - axis.
